In new street additions, Xinghua built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Shuozhou built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Banda Aceh built increasingly disconnected streets over time. For the full network, Xinghua grew more disconnected from 1975 through 1976-1990, then improved, while Shuozhou became progressively more connected and Banda Aceh became progressively more disconnected. Notably, Xinghua had a more sprawly network than Banda Aceh in 1975 but the two have since reversed their relative ranking.
